    One of my serpaes I got today isn't showing that black vertical mark on its side. It's still juvenile so could that be it? It was like that in the lfs too so could it be due to stress?

    I know there are other tetras very similar to Serpaes. Maybe another species got mixed in?

    Can you post a pic?

    There are a couple of tetras that look like serpae tetras such as flame tetra and bentos tetra

    The tetras might also be stressed

    Sorry it's so bad. Out of the 4 serpaes I got yesterday only 2 had the vertical black stripe. The other 2 had somewhat of the stripe but not all.

    It is a variable character. Different populations from the wild have been interbred commercially, so the variation occurs within a single spawn, rather than being a location/population characteristic.

    So @chromedome52 they'll always look different from each other? I wanted them to all look similar because it will look natural when the school

    variations are natural, I guess you mean uniform :)

    Some sources have more uniformly marked fish, as they only started with one population for breeding. I suspect that yours will never have the exact same markings. Sorry.

    I mean, the two were talking about show a faded mark. So like half of it is showing so it looks like a black dot almost
